Only pay workers for the time they spent working.
You are only required to pay the worker for the actual time they spent working your Shift Gig, so it is completely acceptable to send them home if they finish early. Both workers and the Requesters can terminate the Shift Gig at any time for any reason.
If a worker completes your task in less time than expected, or circumstances prevent the Shift Gig from continuing, you can end the Shift Gig. The worker payment is always based off of the worker's start and end time, not the Shift Gig’s scheduled start and end time.
In addition, once the Shift Gig is completed, Requesters have the option to edit worker timesheets to ensure the correct start time, end time, and any unpaid breaks are accounted for. Once you are satisfied with the worker timesheet you can submit it to finalize the worker’s payment.
